Description

This application claims benefit of U.S. Provisional Application No. 60/727,448, filed Oct. 18, 2005, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 05 50249, filed Jan. 28, 2005, the contents of which are also incorporated herein by reference.

Disclosed herein is a hair treatment method comprising successively applying to the hair at least one reducing agent, at least one rinsing material, at least one entity chosen from polymers, cerids, and sterids, at least one heat source, and at least one fixing agent.

Hair styling products making it possible to give a hair style particular original shapes may include, for example, gels, solutions, and foams containing a fixing polymer. The inconvenience associated with such a product type lies in that holding the hair in place may be limited over time, for example, the shape may be lost when the hair is being shampooed for the first time.

In addition, permanent treatments for keratin fibers are known. Such methods comprise a first step comprising the opening of disulfide links of the keratin (cystine) using a composition containing a reducing agent, and, after the hair has been optionally rinsed, recreating said disulfide links by applying on the smoothed or previously stretched hair, using appropriate means such as hair-curlers, an oxidizing composition, also referred to as fixing agent, so as to impart to the hair the desired shape. Such a technique indiscriminately may allow for the waving, straightening, backcombing, and/or smoothing of the hair.

It is desirable to provide novel compositions which allow the user to fix the hair durably in very different shapes.

The present inventor has therefore developed a method for treating keratinous fibers comprising:

  • coating the keratinous fibers with at least one reducing agent,
  • rinsing the keratinous fibers,
  • coating the keratinous fibers with a cosmetic composition comprising at least one non-crystalline or semi-crystalline fixing polymer, and/or at least one cerid, and/or at least one sterid,
  • raising the temperature of the keratinous fibers, using at least one heat source, up to a temperature ranging from 50 to 280° C., and
  • coating the keratinous fibers with at least one oxidizing agent.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are incorporated herein and constitute a part of this specification, illustrate several embodiments of the presently disclosed invention, and together with the description, serve to explain the principles of the invention.

FIGS. 1A to 1K illustrate sectional views of branches of various heating tongs,

FIGS. 2A to 2C illustrate sectional and top views of molds adaptable on heating tongs, and

FIGS. 3A to 3J illustrate sectional view of tongs comprising a single heating element.

The heat source helps to impart the shape to the hair. The heat source may be applied to the hair by pressing the hair continuously or discontinuously.

In at least one embodiment, the heat source may be a smoothing tong, curling tong, or waving tong, allowing the user to impart original shapes to the hair locks.

The tong may allow the user to impart to the hair any pattern and/or shape type, and, for example, projecting or “curved” shapes, such as circular and elliptical shapes, for example, spots, ovals, rectangular, and hexagonal shapes, small squares, rectangles, hexagons, triangles, patterns imitating hair styles such as plaits, or any other patterns representing any object or image shape.

For “imparting” the shape or the pattern to the hair, tweezers may be pressed around a hair lock onto which the reducing agent and the cosmetic composition containing at least one non crystalline or semi-crystalline polymer, and/or at least one cerid, and/or at least one sterid have been applied.

Thus, the heating tong may comprise tweezers with two branches, the section of each branch having any shape, for example, chosen from rectangular, curved, triangular, and polyhexagonal shapes.

The branches of the tong may have symmetrical shapes or shapes complementary to each other. One branch or both branches of the tong may be capable of being heated. Non-limiting examples of branches of various heating tongs are illustrated in a sectional view in FIG. 1.

In one embodiment of the present disclosure, the branches of the tong may be flat, symmetrically curved, complementarily curved, symmetrically triangular, complementarily triangular, symmetrically polyhexagonal, or complementarily polyhexagonal.

In order to impart original shapes to the hair locks, the branches of the tong may be coated with a mold having a variable shape.

Non-limiting examples of molds able to be adapted to the surface of the branches of a tong are illustrated in FIGS. 2A, 2B, and 2C.

As is illustrated in FIG. 2, the molds may have a width “I” ranging from 0.5 to 30 cm, for example, from 2 to 15 cm, a length “L” ranging from 2 to 30 cm, for example, from 5 to 15 cm. In at least one embodiment, the molds may have dimensions as shown in FIG. 2, wherein:

  • a1, b1, and c1 may range from 0.1 to 5 cm, for example, from 0.1 to 1.5 cm,
  • a2, b2, and c2 may range from 0.1 to 10 cm, for example, from 0.5 to 5 cm, and
  • a3, b3, and c3 may range from 0.1 to 10 cm, for example, from 0.5 to 5 cm.
    However, it is to be understood that these dimensions are merely exemplary and the molds may have any dimensions suitable for imparting shape to the hair.

In another embodiment, the heat source may be a tong comprising a single heating element around which the keratinous fibers may be twisted. Such an element may have a varied shape, for example, a cylindrical or parallelepiped shape. Non-limiting examples of such heating sources are illustrated in FIG. 3.

The heat source may thus comprise one element with a section having a shape chosen from circular, oval, squared, rectangular, parallelepipedic, trapezoid, pentagonal, hexagonal, octagonal, and triangular shapes.

In at least one embodiment of the present disclosure, the step comprising coating the keratinous fibers with at least one cosmetic composition comprising at least one fixing polymer, and/or at least one cerid, and/or at least one sterid and the step comprising raising the temperature of the keratinous fibers may be carried out simultaneously.

The above embodiment may be implemented using a device comprising a heat source and a tank containing a cosmetic composition comprising at least one fixing polymer, and/or at least one cerid, and/or at least one sterid. For example, such a conditioning and application device may comprise:

a tank, either heated or not heated, containing a composition comprising at least one non crystalline or semi-crystalline polymer, and/or at least one cerid, and/or at least one sterid,

a coating device, and

a heating means arranged on both sides of the coating device allowing the user to heat the fibers prior to, simultaneously with, and/or after coating the fibers with the cosmetic composition (at a temperature higher than the melting point of the cosmetic composition).

The heating means may therefore serve as a coater.

The at least one reducing agent may be chosen from thiols such as thioglycolic acid, thiolactic acid, 3-mercaptopropionic acid, thiomalic acid, 2,3-dimercaptosuccinic acid, cysteine, N-glycyl-L-cysteine, and L-cysteinylglycine as well as the esters and salts thereof; thioglycerol, cysteamine, and the C1-C4 acylated derivates thereof; N-mesylcysteamine; N-acetylcysteine; sugar N-mercaptoalkylamides such as N-(mercapto-2-ethyl)gluconamide; pantetheine; N-(mercaptoalkyl)-ω-hydroxy alkylamides, for example, those disclosed in European Patent Application No. 0 354 835; N-mono or N,N-dialkylmercapto-4 butyramides, for example, those disclosed in European Patent Application No. 0 368 763; aminomercapto-alkylamides, for example, those disclosed in European Patent Application No. 0 432 000; derivatives of N-(mercapto-alkyl)succinamic acids and N-(mercaptoalkyl)succinimides, for example, those disclosed in European Patent Application No. 0 465 342; alkylamino mercaptoalkylamides, for example, those disclosed in European Patent Application No. 0 514 282; an azeotropic mixture of 2-hydroxypropyl thioglycolate and (2-hydroxy-1-methyl)ethyl thioglycolate, such as that disclosed in French Patent Application No. 2 679 448; mercaptoalkylaminoamides, for example, those disclosed in French Patent Application No. 2 692 481; and N-mercaptoalkylalkane diamides, for example, those disclosed in European Patent Application No. 0 653 202.

In one embodiment, the at least one reducing agent may be chosen from thioglycolic acid, cysteine, and derivatives thereof. In another embodiment, the reducing agent may be used in an aqueous solution.

When a thiol is being used as the reducing agent, for example, thioglycolic acid, the reducing agent may be used in a solution, in a concentration ranging from 0.05 to 1 M, the pH of the aqueous solution may range from 6.5 to 9, and the contacting time generally may range from 1 to 15 minutes, for example, from 5 to 10 minutes.
